18QHTF21-10.900-OE

Overview

The 18QHTF21-10.900-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 10.9 MHz. It utilizes LVCMOS output logic and supports a supply voltage range compatible with 1.8V operation. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, specifically identified as SMD2016-4P, suitable for surface-mount assembly. The component is designed to provide precise frequency generation and timing signals for electronic circuits.

Feature Summary

• Provides stable 10.9 MHz frequency generation using LVCMOS output logic
• Includes hardware enable and disable functionality for power control
• Utilizes a compact 4-SMD No Lead surface-mount package

Applications

• General purpose timing signal generation
• Clock source for digital circuits requiring 1.8V logic levels
• Embedded systems requiring precise frequency references

Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current documentation to ensure compatibility with required enable/disable pin configurations and output drive strengths. Confirm that the 1.8V supply voltage aligns with the target system design before procurement. Ensure the SMD2016-4P footprint matches the PCB layout requirements.

Selection Notes

Select this component when a low-profile 2.0mm x 1.6mm oscillator is required for 10.9 MHz applications. It is appropriate for designs necessitating LVCMOS outputs and active high/low enable controls. Consider the 1.8V operating voltage constraint during system architecture planning to ensure proper interfacing with downstream logic components.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal and clock oscillator products. The company has a long history in frequency control manufacturing. This specific model represents a standard XO variant within their portfolio, distinguished by its small form factor and specific frequency rating.

Replacement Considerations

Direct substitutes include other 10.9 MHz LVCMOS oscillators in 4-SMD packages with similar dimensions. Verify pinout compatibility and electrical specifications such as load capacitance and drive strength before substitution.
